I attended Vigil Mass today. In the Gospel reading from Luke 12, Jesus told the parable of the rich fool. He said, "God said to the rich man, 'You fool, this night your life will be demanded of you; and the things you have prepared, to whom will they belong?' Thus will it be for all who store up treasure for themselves but are not rich in what matters to God." Jesus wants us to store up treasures in heaven. I think we all know when we do something whether we are becoming rich in what matters to God. If not, then we'll have wasted our time on earth.
